Harry Potter star Tom Felton was carried to a Wisconsin golf course after collapsing during a pre-Ryder Cup celebrity match.
The actor, who turned 34 on Wednesday, suffered a “medical incident” and was taken to a “local hospital” for treatment, the PGA of America said.
Pictures showed him conscious while he was being carried away in a cart.
Mr Felton is known for playing Harry Potter’s rival Draco Malfoy in the film franchise.
As an avid golfer, Mr. Felton represented Europe together with former professional ice hockey player Teemu Selanne from Finland at the celebrity tournament in Whistling Straits.
They played in 1980 against the US ice hockey captain Mike Eurzione and the Olympic speed skater Dan Jansen.
The PGA of America statement said no details regarding his condition are available.
